海洋运输部门正凭借 Harbor Charger 的首航迎来绿色科技的转折点，这是纽约价值 3,300 万美元的混合动力电力公共渡轮。它负责运送 1,200 名乘客和 30 辆车辆至面积 69.6 公顷（原为 172 英亩）的 Governors Island，其运作速度比每日消耗 1,590 公升（原为 420 加仑）燃料的前代渡轮快上 66%。该渡轮配备 132 个锂离子电池组，可仅凭电力运行 90 分钟，每年可节省 200,000 美元燃料费，并减少 544.3 公吨（原为 600 吨）的二氧化碳排放量。一旦安装码头快速充电站，将能完全淘汰柴油，每年可再减少 725.7 公吨（原为 800 吨）的二氧化碳。

在加州，San Francisco Bay Ferry 将于 2027 年初启用一艘高速且完全由电池驱动的电力客运渡轮。在 5,500 万美元联邦拨款的支持下，这艘可容纳 150 名乘客的船只将进行前往 161.9 公顷（原为 400 英亩） Treasure Island 的八分钟航程。该机构正在采购五艘电力船只，以在 2035 年前打造一支完全零排放的船队。Thomas Hall 指出，船只设计省略了传统贩卖部以减轻重量。在国际上，丹麦以风力发电运作的电子渡轮 Ellen 保持著世界纪录，单次充电即可航行 40.7 公里（原为 22 海里），每年可消除 2,041.2 公吨（原为 2,250 吨）的二氧化碳。

为了避开水阻，斯德哥尔摩由 Candela 制造的 P-12 水翼船在时速超过 29.6 公里/小时（原为 16 节）时，会将其碳纤维船体提升至水面之上，从而减少 80% 的能源消耗。这项水翼技术正被华盛顿特区考虑用于通勤运输。尽管营运商必须克服船员培训挑战以及「渡轮焦虑」（ferrynoia）——即担心软体故障或电池单元损坏会中断大众所依赖的交通——但像 Clare Newman 这样的领导者强调，投资具有可扩充电池容量的混合动力船只，能为船队未来过渡至完全电力运作做好准备。

The maritime sector is reaching a green technology tipping point with the debut of the Harbor Charger, New York’s $33 million hybrid-electric public ferry. Transporting 1,200 passengers and 30 vehicles to the 69.6-hectare (originally 172-acre) Governors Island, it operates 66% faster than the predecessor that consumed 1,590 liters (originally 420 gallons) of fuel daily. Equipped with 132 lithium-ion battery packs, it runs on electricity for 90 minutes, saving $200,000 in fuel and reducing annual carbon dioxide emissions by 544.3 metric tons (originally 600 tons). Dockside rapid-charging will eliminate diesel completely, saving another 725.7 metric tons (originally 800 tons) of carbon dioxide yearly.

In California, San Francisco Bay Ferry will launch a high-speed, fully battery-electric passenger vessel in early 2027. Backed by a $55 million federal grant, this 150-passenger ship will make an eight-minute trip to the 161.9-hectare (originally 400-acre) Treasure Island. The agency is acquiring five electric vessels to build a zero-emission fleet by 2035. Thomas Hall noted that designs omit concession areas to save weight. Internationally, Denmark’s wind-powered e-ferry Ellen holds a world record, sailing 40.7 kilometers (originally 22 nautical miles) on one charge, eliminating 2,041.2 metric tons (originally 2,250 tons) of carbon dioxide annually.

To bypass water resistance, Stockholm’s Candela P-12 hydrofoil lifts its hull above water when exceeding 29.6 km/h (originally 16 knots), cutting energy use by 80%. This hydrofoil is being considered for use in Washington, D.C. Although operators must overcome crew training challenges and "ferrynoia"—the fear of software or battery failures halting transit—leaders like Clare Newman emphasize that investing in hybrid vessels with expandable battery storage prepares fleets for a fully electric future.
